Given numbers are 331,774,180,432

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 331,774,180,432 is 30743280.

Find LCM of 331,774,180,432 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 3 x 331 x 43 x 5 x 12 = 30743280

Therefore, the lowest common multiple of 331,774,180,432 is 30743280.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

331 x 774 x 180 x 432 = 19921645440

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

331 : 1, 331

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,774,180,432, is 1.

Now, the common factors can be found like this.

331:331

774:2x 3x 3x 43

180:2x 2x 3x 3x 5

432:2x 2x 2x 2x 3x 3x 3

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 3x 3x 3x 3 = 648

Therefore, the value for common factors is 648.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 19921645440/(1x648)

LCM = 19921645440/648

LCM = 30743280

Thus, we can understand that the LCM of 331,774,180,432 is 30743280.
